Agricultural societies cannot exist without staple crops.  Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods.  All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams.  Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.
 
Which of the following is an assumption on which the argument depends?
原文说All the recorded staple crops grown in western Africa were introduced from elsewhere,感觉和意思沾边，因为B说没有本地植物被种作为staple food crops 正确答案A的意思看不太懂，好像是说不发展staple crops的时间问题，原文说发展staple crops没说不发展啊，请老师翻译一下A选项的准确意思，然后解释一下为啥A是原文的假设
